Altair 700: compact, quiet and cold climate from the 9,000.
Two sizes, 9,000 and 12,000 BTU/h, both ENERGY STAR cold-climate certified. Wi-Fi is built in and the indoor unit goes down to 19 dB(A) on quiet speed, according to Fujitsu. It heats down to -15 °C: the right pick for a bedroom, an office or a basement, alongside your main heating in winter.
Altair, in the Eagle
Altair and its two neighbours in the constellation of the Eagle, placed from the catalogue. Fujitsu does not explain its series names.
The small wall unit with the cold-climate mark.
Six facts from Fujitsu documents and the ENERGY STAR list. Sources are at the bottom of the page.
Both sizes, 9,000 and 12,000, are ENERGY STAR Cold Climate certified.
On its quiet speed, the indoor unit goes down to 19 dB(A), according to Fujitsu: a lab measurement.
Built-in Wi-Fi: it is the only Altair series that needs no adapter.
Same indoor size as the Altair 500 at 9,000 and 12,000, but more heat at -15 °C: 10,300 and 10,600 BTU/h against 7,100 and 8,500.
Same ENERGY STAR value at -8 °C as the Altair 500 12,000, but $1,044 of LogisVert instead of $435, thanks to the Cold Climate mark.
The first of Fujitsu’s five R-32 wall series on the market, in May 2024 per ENERGY STAR.
Better-Tier: the best of the Altair.
All three Altair heat down to -15 °C. What puts the Altair 700 on top: the cold-climate mark from the 9,000 and built-in Wi-Fi. To heat lower, step up to the Orion.
9,000 or 12,000 BTU/h.

For main heating in deep cold: the Orion XLTH goes down to -26 °C and has the heated base pan; the Altair 700 is quieter and lighter.
Built-in Wi-Fi and a 10 °C minimum heat mode.
What Fujitsu puts in every Altair 700.
Built-in Wi-Fi: you control the unit with the AIRSTAGE Mobile app, no adapter needed.
No automatic cut-out in cold weather, according to Fujitsu.
Minimum heat mode: the room stays at 10 °C, above freezing.
Two filters: apple catechin (3 to 12 months) and ion deodorizing (3 years, washable).
Powerful mode: 20 minutes at maximum airflow and compressor speed.
Four fan speeds, plus auto.
Outdoor low-noise mode: 3 dB quieter, according to Fujitsu.
Works with Fujitsu’s KAGAMI UTY-RVRU wall controller and UTY-RNRUZ5 touch controller.
Minimum heat mode: the room stays at 10 °C, above freezing, handy for a cottage or a little-used basement. Fujitsu publishes no capacity below -15 °C for the Altair 700.
19 dB(A): below a whisper.
Place the Altair 700 on the scale of everyday sounds. On quiet speed it is the quietest Fujitsu R-32 wall unit, tied with the Altair 500 at 9,000 and 12,000.
| Model | Indoor, quiet speed | Indoor, high speed | Outdoor unit |
|---|---|---|---|
| Altair 700 9,000 BTU/h | 19 dB(A) | 40 dB(A) | 47 dB(A) |
| Altair 700 12,000 BTU/h | 19 dB(A) | 40 dB(A) | 50 dB(A) |
Levels published by Fujitsu, measured in a lab; at home, the room, the furniture and the distance change what you hear. Scale: Government of Québec reference points.
Up to 20 m of line set.
Drag the sliders to place the outdoor unit: the tool applies Fujitsu’s limits and the refrigerant to add beyond the pre-charge.
| Model | Max length | Max height | Pre-charge | Minimum |
|---|---|---|---|---|
| Altair 700 9,000 BTU/h | 20 m | 15 m | 15 m | 3 m |
| Altair 700 12,000 BTU/h | 20 m | 15 m | 15 m | 3 m |
$1,044 for the 12,000, nothing for the 9,000.
Both sizes are cold climate, but LogisVert requires at least 12,000 BTU/h nominal. The 12,000 gets $120 per 1,000 BTU/h of heat rated at -8 °C.
| Model | Indicative amount | Calculation |
|---|---|---|
| Altair 700 9,000 BTU/h | $0 | – |
| Altair 700 12,000 BTU/h | $1,044 | 8,700 BTU/h ÷ 1,000 × $120 = $1,044 |
Since November 26, 2025, only ENERGY STAR certified heat pumps qualify.
The outdoor unit must be at least 12,000 BTU/h nominal in cooling.
The grant never exceeds the purchase and installation cost, before taxes.
You apply no later than nine months after installation.

What people ask us about the Altair 700.
No question matches. Call us at 514 316-2973.
Yes. Both sizes are ENERGY STAR Cold Climate certified.
Down to -15 °C outdoors, with no automatic cut-out in cold weather, according to Fujitsu.
10,300 BTU/h for the 9,000 and 10,600 BTU/h for the 12,000, per ENERGY STAR.
Yes. Wi-Fi is built in and works with the AIRSTAGE Mobile app. No adapter is needed.
On its quiet speed, the indoor unit goes down to 19 dB(A) in cooling, according to Fujitsu. That is a lab measurement.
Same indoor size, but the Altair 700 is Cold Climate certified, gives more heat at -15 °C, has built-in Wi-Fi and a higher SEER2. The Altair 500 offers sizes up to 36,000 BTU/h and six fan speeds.
The 12,000 does: $1,044 under Hydro-Québec’s rule. The 9,000 does not, as it is below the 12,000 BTU/h minimum.
Fujitsu does not list one for this series, so your HVAC contractor picks a spot where defrost water drains well.
Up to 20 m of line set and 15 m of height difference, with 15 m pre-charged.
An apple-catechin filter and an ion deodorizing filter, on top of the washable air filter.
Fujitsu specifies 15 A for both sizes, at 208/230 V.
It has a minimum heat mode that holds the room at 10 °C, and built-in Wi-Fi lets you check on it remotely. Below -15 °C, Fujitsu publishes no heating capacity, so your HVAC contractor will tell you whether backup heat is wise.
